定义了对数拓扑指数 LTI( i) ,并在双区理论基础上提出了多环芳烃 ( PAHs)的致癌性与其 LTI( i)之间的定量关系方程 .80个 PAHs的致癌性的计算值与实验结果的相符率达 98% .
The logarithmic topological index LTI (i) was defined and the quantitative relationship between the carcinogenicity of polycyclic aromatic hydrocarbons (PAHs) and its LTI (i) was proposed on the basis of the two-zone theory. The calculated values for carcinogenicity of 80 PAHs The rate of agreement with the experimental results was 98%.
